In the era of network informatization, the Internet of Things has more and more complex requirements for information interaction across trust domains, and cross-domain identity authentication has become the focus of research and attention by security personnel. However, IoT devices often lack computing power and lack of security protection measures. The existing authentication schemes are complex and have poor robustness, which is not suitable for the IoT environment. to address this problem, this paper proposes a lightweight and robust cross-domain authentication scheme based on master-slave blockchain. Our method adopts the master-slave blockchain mode for cross-domain identity authentication, uses the trust evaluation mechanism to measure the reputation value of nodes, and selects nodes with high reputation values as cross-domain communication nodes. Experimental results show that our method is not only more robust than similar methods but also takes less time to complete the authentication.
